Frances Bean Cobain told Us Weekly, "While I'm generally silent on the affairs of my biological mother, her recent tirade has taken a gross turn… I have never been approached by Dave Grohl in more than a platonic way. I'm in a monogamous relationship [with the Rambles' Isaiah Silva], and very happy."

As reported by Gawker, the tirade took place this week on Courtney Love's private Twitter account (@cbabymichelle), which is confined to a conservative 548 followers as of right now. Apparently the Hole singer accused 43-year-old, married Grohl of making a pass at Cobain, claiming the information came from her estranged daughter's roommate and a driver. The ranting singer went on to say that Grohl was "sexually obsessed" with her late husband, Nirvana lead singer Kurt Cobain.

Dave Grohl's camp quickly issued a statement after the diatribe went public, saying, "Unfortunately, Courtney is on another hateful Twitter rant… These new accusations are upsetting, offensive, and absolutely untrue."
